In this paper, a non-isolated high step-up dc-dc converter is presented. The\nproposed converter is composed of an interleaved structure and diode-capacitor\nmultiplier cells for interfacing low-voltage renewable energy sources to\nhigh-voltage distribution buses. The aforementioned topology can provide a very\nhigh voltage gain due to employing the coupled inductors and the\ndiode-capacitor cells. The coupled inductors are connected to the\ndiode-capacitor multiplier cells to achieve the interleaved energy storage in\nthe output side. Furthermore, the proposed topology provides continuous input\ncurrent with low voltage stress on the power devices. The reverse recovery\nproblem of the diodes is reduced. This topology can be operated at a reduced\nduty cycle by adjusting the turn ratio of the coupled inductors. Moreover, the\nperformance comparison between the proposed topology and other converters are\nintroduced. The design considerations operation principle, steady-state\nanalysis, simulation results, and experimental verifications are presented.\nTherefore, a 500-W hardware prototype with an input voltage of 30-V and an\noutput voltage of 1000-V is built to verify the performance and the theoretical\nanalysis.\n
